Specification 01' Letters Patent.

Patented June 23, 1908.

Application filed December 26, 1907. Serial No. 408,174.

To all whom it may concern:

Be it knovm that I, ANDREW B. CHRISTEN- SEN, a citizen of the United States, a' resident of Chicago, in the county of Cook and ,State of Illinois, have invented certain new and useful Improvements in Gearing for Washing-Machines, of which the following is a full, clear, and exact description.

My invention relates to certain improvements in gearing for washing machines.

The invention is designed to overcome certain objectionable features common in washing machines and to otherwise improve the same.

To such end this invention consists in certain novel features of construction and arrangement, a description of which will be found in the following specification and the essential features of which will be more definitely pointed out in the claims.

The invention isclearly illustrated in the drawings furnished herewith in which Figure 1 is a plan view of a washing machine illustrating the preferred form of myinvention. Fig. 2 is a front view thereof. Fig. 3 is a vertical section taken on line 33 Fig. 1. Fig. 4 is a plan view of a bearing late. Fig. 5 is a side view of a modified orin of the invention and Fig. 6 is a vertical section taken on line 66 Fig. 5;

Referring first to Figs. 1 to 4 inclusive, A, represents a tub of ordinary form which is provided with a lid or cover B hinged to the tub by hinges a. lVithin the tub is a dasher C, which is supported in the lid B, and arranged to be glven a rotary reciprocatory motion by the gearing, which forms the subject matter of the present invention.

A bearing plate or bracket 10, is bolted or otherwise secured to the lid B and is formed with an elongated vertical bearing aperture r11, in whichis journaled the dasher shaft 12, of the dasher C. Said bearing plate 10 has three vertically extending studs 13, 14, 15 and a. horizontally extending stud 16, each of which is adapted to receive one of the operating parts 0 the gearing.

The dasher shaft 12, bears upon its upper end a pinion 17, which meshes with a segmental rack 18, formed upon an operating lever 19, which lever is provided with a bearing aperture 20 and'a handle socket 21. The

lever '19, is journaled to oscillate upon the stud 14, and is provided vnth a handle 22, fitted to the handle socket 21. Oscillation of the operating lever 19, will obviously impart to the dasher shaft a rotary reciprocatory, movement through the action of the segmental gear or rack 18 and pinion 17.

'In order that the machine may have an even and easy operation I have provided a fly wheel or balance wheel 23, which is geared to the dasher shaft by mechanism entirely independent'of the operating lever 19, this gearing being so proportioned and arranged, that while the operating lever has a comparatively slow movement, the fly wheel will run at high speed.

A transmitting .member 24, is journaled upon the stud 13, and has a flange 24 which overhangs the pinion 17 so as to protect the user from injury from the pinion 17 and rack 18. Upon the underside of the transmitting member 24, is a segmental rack 25, which meshes with the pinion 1 7. It should be noticed that the operating lever and transmission member 24 lie diametrically opposite each other on either side of the pinion 17, and that the ear'teeth of the racks 18 and 25 oppose eac other With the pinion in between them.

The oscillatory reciprocatory motion of the dasher shaft is transferred to the transmission member giving it an oscillatory movement of some extent and this movement is transmitted to a gear wheel 26 by a pitman 27 which connects the transmission member and gearwheel. Wrist-pins 28, 29 are provided u on the transmission member and gear WheeFrespeotively for engagement with. the pitman. The gear wheel 26 1S journaled upon the stud 15 of the frame 10, and

meshes with a pinion 30, which isformed and backward movement of the transmission member will cause a number of revolutions of the fly-wheel, at high s cad. The operation of the evice is as follows:

Oscillation of the operating lever will impart The fly-wheel is dasher shaft.

a rotary reciprocatory movement to the This movement of the dasher shaft is transmitted to the transmission member in the form of an oscillatory movement, which movement is transformed into a continuous rotary movement of the fly wheel through the agency of the pitman, gear wheel and pinion.

In the form shown in Figs, 5 and 6, th pinion 1 7 is extended to form'a bevel pinion, 17 and the o erating lever 19 contains a bevel segmenta gear 18? which meshes with the power derived from the fi wheel is imparted to the dasher pinion inde endently of the operating lever, and upon t e side of the pinion opposite to the operating lever. The pinion is therefore turned back and forth between the two racks 18-25, and a steady and even movement is imparted to the dasher which is one of the results which it is desired to obtain in machines of this class.

. rota I am well aware that various alterations and modifications of this device are ossible without de arting from the spirit 0' m invention an I do not therefore desire to myself to the exact forms shown and .described. I p

I-claim as new and desire to secure by Letters Patent:'.

1. In a gearing for washing machines, the

combination with a dasher shaft, of an 0 erating lever arranged to impart to said s aft a rotary reciprocatory movement, a fly wheel,

. 2. In a gearing for washing machines, the combination with a dasher shaft and inion, of an operating lever having a rack t ereon meshing with said' pinion, a fl wheel, and connections between the fly w eel and pinion for transforming the rotary reciprocatory movement 'of" they pinion into a continuous movement of the fly wheel.
